SPECIFICATION forming part of Letters Patent No. 504,856, datedSeptember 12, 1893.

Application filed May 2, 1893. Serial No. 472,807- (No model.)

To aZZ whom t may concern:

Be it known that I, JOHANN AICHNER, a citizen of Germany, and a residentof the city of Brooklyn, in the county of Kings, State of New York, haveinvented certain new and .useful Improvements in Carpenters Vises,of

which the following is a specification.

The object of my invention is to provide a new and improved carpentersvise for holding pieces of wood while planing their ends, either atright-angles to `the edges or at an obtuse or acute angle.

The invention'consists in the combination with a fixed jaw, ofguide-bars secured to the same, a movable jaw mounted on said guidebars,means for moving said movable jaw, a beveled piece mounted to move onthe guidebars and to pass into a recess in the fixed jaw and means forcoupling said beveled piece to the movable jaw.

The invention also consists in the construc tion and combination ofparts and details, which will be fully described hereinafter and Iinallypointed out in the claims.

In the accompanying drawings, Figure 1 is a front-view of my improvedcarpenters vise. Fig. 2 is an end-view of the same. Fig. 3 is aplan-view, with the beveled piece drawn out. Fig. 4 is a transversesectional view, on the line l 4, of Fig. 3. Fig. 5 is a plan View, thebeveled piece being within thefixed jaw. Fig. 6 is a transversesectional view, on the line 6 6, of Fig. 5, and Fig. 7 is a transversesectional view, on the line 7 7, of Fig. l, showing the vise reversed.

Similar letters of lreference indicate correspending parts.

The vise is constructed with the fixed jaw A and the movable jaw B. Tothe rear of the fixed jaw A two guide-bars C are fastened, which areL-shaped in cross-section and which are connected at the ends oppositethe ones fastened to the jaw A by a cross-piece D. A brace-bar E isfastened to the cross-piece D and to the back of the fixed jaw. Themovable jaw B is suitably guided on the guidebars C. The fixed jaw A isprovided in its inner side with a triangular recess a, shown in dottedlines in Figs. 3 and 5 and in full lines in Figs. 4 and 6. A slidingtriangular or beveled piece H of the same height as the jaws A and B isarranged between the same and is of such size and such depth thatit canpass into the recess a and fit snugly in the same. Said beveled piece His provided with an extension F passing through the slot between theguide-bars C, on which extension a cross-piece F is formed, for thepurpose of guiding said beveled piece H on the guidebars C. A springcatch .I is fastened on the back of the beveled piece H and is adaptedto engage a pin K projecting from the back of the movable jaw B. Ascrew-spindle L provided with a crank-handle M is mounted to turn in abearing N on the cross-piece D,which spindle L is screwed through a nutO on the end of the jaw B and can pass into an aperture P in said jaw B,as shown in dotted lines in Fig. 3. The tops of the jaws A and B are atright-angles to the front of the jaws, as shown at b, Fig. 2, and thebottom of the jaws is at an angle of twenty-two and one-half degrees tothe front of the jaws, as shown at d, Fig. 2. The two sides of thebeveled pieceH are at right-angles to each other and each at an angle offorty-five degrees to a plane parallel with the front of the jaws.

The device is used in the following manner: r1`he same is clamped to anordinary carpenters work-bench in such a manner that the top fm isparallel with thetop of the bench. If a bevel of forty-five degrees isto be cut, the movable jaw B is moved a greater or less distance fromthe fixed jaw, to permit of inserting the piece to be cut, which piecerests on the top of the beveled piece H. The projecting part is thenplaned off flush with the surface m. If the piece is to be cut 0E atright-angles, the movable jaw B is moved against the jaw A and thespring-catch J is raised so as to disengage it from the pin K, wherebythe beveled piece H is unlocked from the movable Ajaw B. If now the jawB is moved from the jaw Athe beveled piece H remains in the recess@ ofthe fixed jaw A, as shown in Fig. 6, and the piece to be cut o can beplaced between the jaws A and B. The piece can then be cut 0E atright-angles by planing along the tops fm of the jaws. In order to cutbevels of twenty-two and one-half IOO degrees and sixty-seven andone-half degrees,

twenty-two and one-half degrees isdesired, the beveled-piece H remainsin the recess a of the fixed jaw A and the board is clamped between thefixed and movable jaws and is cut 0E along the inclined face 0 of thevise, which is at an angle of twenty-two and onehalf degrees to thefront of the jaws C. In ease the piece is to be cnt at an angle ofsixtyseven and one-half degrees, the beveled piece H is locked to themovable jaw B so as to be Withdrawn from the recess a. The board to becut at an angle of sixty-seven and one-half degrees is then placed onthe upper surface of the beveled piece H and `the projecting part is cutoft' Hush with the inclined face a of fthe-jaws A and B.

`Having` thusl described myfinvention, I claim las new. and desire tosecure by Letters Patentlll. InY ay carpenters vise,l the combinationwith a fixed jaw, of guide-bars secured to the same, amovable jawmounted to slide on said guide-tracks, and means for. moving saidmovable jaw, one surface of said jaws being` at lright-angl es to thefronts of the jaws and the other face at an an gle of twenty-two andonetWentieth-f degrees, and a beveled movable piece mounted on theguide-bars, substanwith a recess, of guide-bars secured to said fixedjaw, a'movablejaw on said guide-bars, means for moving said jaw, abeveled piece mounted to travel onlsaid. guide-bars and-to pass into-the `rece'ss in the xed` jawy and ymeans for coupling said:beveledpiece to the movable jaw, substantially as:set-fortht Intestimony that I claim the foregoing as my invention Ihave signedmynarne in presence of'two subscribing witnesses.
